Are Older Games More Satisfying?

Kwirl asks: "While the computer and console gaming industry is growing at a remarkable pace, the focus is usually on better graphics as opposed to stronger gameplay and plot development/story arc. I personally have several titles (Sims2, Half-Life2, Doom 3, MSFS2004, Unreal 2004) sitting on my shelf that were amazing games, but just couldn't hold my interest for long enough to really be considered a worthwhile investment. In the last couple of years I had thought that the answer to my gaming needs would come in the form of MMORPG's. I have purchased and played many of them, but all seem to come to a stagnant point where I recognize that only addiction would drive me deeper into the game, and not better gameplay (Dark Age of Camelot, World of Warcraft, City of Heroes, Everquest II). In truth, I have found myself spending more time playing old MUD's (TorilMud, Medievia) again, or even amusing web-based games ( KingdomofLoathing, PimpWar, NeoPets). I am curious to know how many other people here find themselves walking intentionally backwards along the technological timeline of games for your personal expenditure of free time? What games/sites do you feel give you the best return of satisfaction versus time spent playing the game over the long haul?"
